Preliminary Research on the Uptake Behavior of Ammonium Molybdophosphate for Cesium and the Corresponding Structural Transformation

Abstract:

In this work, Ammonium Molybdophosphate (AMP) was synthesized and the adsorption of Cs onto it under different initial pH conditions was investigated. The results show the negative effect of the hydronium and hydroxyl irons on the uptake of Cs while the iron-exchange capacity can reach 144.8 mg/g. In addition, the structure differences between AMP samples before and after Cs adsorption were examined by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and Raman technique. The results show that the Keggin structure of AMP stayed unchanged while new bonds arose after the Cs adsorption.
